My neighbor's desktop computer ASUS Essentio Model CM6850 needs a cpu fan,
it's making a lot of noise and not spinning up to speed, sounds like a bad
bearing, the fan is model AUB0812VH.

How can I look up the part number for that exact item so I can replace the
fan with a replacement the software will be able to monitor?

I took a chance and bought a same model fan but with a brown instead of red
wire (originals are blue black red yellow) and the machine wouldn't boot -
it didn't detect the fan. Thank God I didn't blow the m/b.

Any suggestions would be appreciated.

Nothing special about that fan that I can see -- just a bog-standard 80mm
4-pin cooling fan which should be available from a dozen makers. Here is
the exact item at Amazon:

https://www.amazon.com/Delta-AUB0812.../dp/B00H0B3XS8

but there are similar items for 2/3 the price although scrimping on a
cooling fan is probably a bad idea in most cases unless you know the maker
well and trust them.
